Sky Map for Android helps you find stars, planets, and constellations

Sky Map is an application for Android that was developed by some Google employees. It makes use of an Android device’s built-in GPS, compass, and accelerometer to identify the constellations seen in the sky, or to help you find a particular celestial body by pointing you in the right direction.

All users have to do is launch the app and hold the phone up to the sky. Sky Map does the rest by making use of all of the phone’s sensors. You can think of it as the star gazer’s version of Enkin.
